FAQ

Q: Is the IC695PBM300 a CPU?
A: No. The IC695PBM300 is a communication interface module, not a processor. It occupies one backplane slot and is programmed by the host RX3i CPU.

Q: What is the difference between IC695PBM300-BA, -CC, and -EC?
A: These are different hardware/firmware revisions. The -CC and -EC versions include enhanced features and firmware improvements. Verify compatibility with your application before ordering.

Q: What is the maximum cable length?
A: At 12 Mbit/s: 100 m; at 1.5 Mbit/s: 200 m; at 93.75 kbit/s: 1,200 m (per PROFIBUS EN 50170).

Installation Guide

1. Power down the RX3i rack (or use hot-swap in non-hazardous zones).
2. Insert the IC695PBM300 into any slot of the RX3i universal backplane.
3. Connect the PROFIBUS-DP cable to the 9-pin Sub-D connector.
4. Install termination resistors at both ends of the PROFIBUS network.
5. Configure slave device parameters via Machine Edition software.
6. Verify network communication using module status LEDs.

Selection Tips

• For PROFINET networks, consider IC695PNC001 instead.
• Verify all PROFIBUS slave devices support the selected baud rate.
• Ensure CPU firmware is version 2.9 or later.
• Use shielded twisted-pair PROFIBUS cable for reliable communication.
• Enable termination only at the two electrical ends of the network segment.
